Meeting Abstract P2-74  Sunday, Jan. 5  A Novel Approach to an Old Question: Evaluation of Ecological Breeding Strategies in Sea Turtles MYRE, B*; GUENTZEL, N; MACKENZIE, DS; TAMU bmyre@bio.tamu.edu Sea turtles have been historically classified as capital breeders, so they should possess a store of energy (e.g., fat) at the beginning of the breeding season that they […]

Meeting Abstract P2-88  Sunday, Jan. 5  A Comparison of Stereotypic and Anticipatory Behavior in Cougars (Puma concolor) and Lions (Panthera leo) from Zoo to Sanctuary BABB, MH*; LOHMANN, C; University of North Carolina at Chapel Hill; University of North Carolina at Chapel Hill mattbabb@live.unc.edu A core pillar of animal behavior research is that environment can profoundly affect […]

Meeting Abstract P2-144  Sunday, Jan. 5  13C-Glucose oxidation testing in laboratory mice: effects of dose, temperature, and nutritional state MCCUE, MD*; LIGHTON, JRB; Sable Systems International; Sable Systems International mmccue@sablesys.com Glucose is the predominant fuel source for most animal tissues. We employed an experimental approach called glucose oxidation testing to quantify glucose oxidation in real time. Laboratory […]

SAVAGE, R.M.*; MEIKLEJOHN, D.A.: hunchback Homologues in Annelids. We are interested in how body plans are patterned and have focused on characterizing homologues to the Drosophilagap gene hunchback (hb) in two annelid classes. The hb gene encodes a C2H2 zinc-finger transcription factor that plays a pivotal role in fly pattern formation. We are using a […]

Beachum, C.*; Strange, R.: an evaluation of phylogeny inference programs and packages Phylogenetic inferences from large data sets can be problematic, with conflict between precision and minimal computer time determining the design of computer packages. We analyzed two large DNA data sets obtained from GenBank and a smaller homoplasy-rich morphological data set to demonstrate inconsistencies […]

BRAINERD, E.L.; LANDBERG, T.*: Ventilatory Mechanics of an Elongate Aquatic Salamander: Amphiuma tridactylum We investigated the mechanism of lung ventilation in an aquatic salamander, Amphiuma tridactylum. Breathing episodes, which occur at intervals ranging from less than 1 to 50 min, are characterized by a single large exhalation followed immediately by a variable number of buccal […]

Mara S. Zimmerman: Variation in brook stickleback (Culaea inconstans) size and shape associated with different predator communities The present study explores the association of morphological traits of brook sticklebacks (Culaea inconstans) with two types of predator communities. Stickleback populations associated with these predator communities differ in the size at which they are vulnerable to predation. […]

Cusack, B.J.*; Niewiarowski, P.H.: Variation In Endurance In The Fence Lizard, Sceloporus undulatus: The Effect Of Temperature, Behavior, And Morphology We measured the thermal sensitivity of endurance capacity, preferred body temperatures, activity body temperatures, and several morphological characteristics of Sceloporus undulatus from Nebraska and Ohio. Overall, S. undulatus from Nebraska had higher endurance than Ohio […]
